摘要
This paper analyzes the merits and demerits of the traditional plots analysis method,the fuzzy equivalence clustering method and the fuzzy C-means clustering method (FCM). Then it proposes a synthetical method. This method is more accurate and reasonable according to the merits and demerits mentioned above when the above three methods are used alone. This synthetical method is applied to the group number and the superiority trends of joint occurrence in the rock mass at-555 levels in Sanshandao gold mine.
